15 Claims. (Cl. 53-66) This invention relates to bundle wrappingmachines, particularly machines for wrapping bundles or stacks ofnewspapers.

The object of the invention is to provide means for applying strips orlengths of wrapping paper to the underside of a bundle or stack ofnewspapers preparatory to a subsequent wrapping-up operation.

According to this invention bundles to be wrapped are carried by aconveyor. A web of paper is fed from beneath the conveyor to a positionabove the upper surface of the conveyor and in front of the bundle. Thisweb is fed with the bundle as it travels over the conveyor and issevered after the paper has travelled a predetermined distance along theconveyor whereby a length of wrapping paper is provided beneath thebundle and having free ends at each end of the bundle adapted to beturned up and wrapped around the bundle by a subseveyor for severing theweb after a predetermined stripor length of paper has been fed beneaththe bundle.

A still further object of the invention is to provide control means forfirst feeding the web of paper to the conveyor beneath the bundle andsubsequently severing the web after the desired length of paper had beenfed beneath the bundle.

Finally, it is an object of this invention to provide means for quicklyand easily mounting a roll of wrapping paper in position for feeding tothe conveyor and applying braking torque thereto.

The above and other objects are achieved by the constructions andcombinations hereafter particularly described and illustrated in theaccompanying specifications and drawings and claimed in the claimsappended thereto.

In the accompanying drawings:

Figure 8 is a top perspective view on an enlarged scale of the webfeeding and cutting mechanism; and

Figure 9 is a schematic view of the control'operating airand electricalcircuit.

In the drawings corresponding remarks refer to corresponding parts inthe various figures.

The device comprises a frame 1 supporting three conveyor sections A, B,and C. Sections A and C are provided with roller flight conveyors 2 and2 continuously driven from left to right. enter conveyor section A fromthe left, either delivered by another conveyor or manually placedthereon. Section B is located between sections A and C and contains thewrapper feeding and severing mechanism hereafter described.

Flight conveyor 2 comprises a plurality of rollers rotatably mounted ateach end on endless chains which pass around sprockets at each end ofthe conveyor. Flight conveyor 2 is driven by a motor or other suitablesource of power. The shaft of one of the flight conveyor sprocketsextends beyond the frame 1. Secured to the outer end of this shaft issprocket 5. Flight conveyor 2 is constructed similarly to flightconveyor 2 and secured to the outer end of one of its shafts is sprocket4. See Figures 4 and 5. Roller chain 3 passes over sprockets 4 and 5.Operation of flight conveyor 2 causes sprocket 5 to rotate thus turningroller chain 3 and rotating sprocket 4. Rotation of sprocket 4 causesflight conveyor 2 to be driven in synchronism with flight conveyor 2.

Section B is made up of four driven rollers 6, 7, 8 and 9. Rollers 6, 7and 9 are driven by chain 10 which drives sprockets 11, 12 and 13secured to shafts of rollers 6, 7 and 9. Roller 8 is driven from chain 3which is driven by flight conveyor 2 and drives flight conveyor 2*".Chain 3 rotates sprocket 14 which is secured to a shaft which passesthrough and is journalled in frame 1.

Within the frame another sprocket 15 is secured to the shaft. sprocket15 through the medium of chain 17. Sprocket 16 rotates roller 8. Thesprocket sizes and roller diameters are so selected that the surfacespeed of the rollers of conveyor section B progressively increases.

A web of paper 19 is fed from roller paper 20 or 21 as shown in Figure 2over idler roll 22 or 22 through guides 23 and 24 and then around drivenconveyor roller 8. The guides 23 and 24 comprise a plurality of spacedresilient curved strips. Guides 23 are located adjacent roller 8. Guides24 are slightly spaced therefrom and curved at their upper ends so as todirect the paper in the direction of travel of the conveyor. The lowerends of the guides 23 and 24 are outwardly directed to permit insertionof the end of the web between the guides for threading the paper readyfor the initial operation.

The operation of the feeding and severing mechanism is more particularlyshown in enlarged views 6, 7 and 8.

The following means is provided for feeding the web of wrapping paper.Roller 25 is journalled on a pair of arms 26 of shaft 26. Arm 27 issecured to and extends from shaft 26 and is pivoted to the end of thepiston 28 of an air cylinder 28. Actuation of the piston in an upwarddirection moves arm 27 which turns shaft 26, causing arms 26 to moveroller 25 against the driven conveyor roller 8 squeezing the paper web19 between the two rollers and by virtue of friction of paper againstthe roller 8 causes the paper web to feed upward. When the piston ofcylinder 28 is retracted, springs 27 withdraws the roller 25 from theroller 8 and the paper no longer feeds. The roller 25 thus acts as apressure mem her for pressing the web of wrapping paper against the feedroll 8 to cause the latter to feed paper from below the plane or surfaceof the conveyor 2 and along said surface beneath a stack 01' bundle ofnewspapers.

Rotatably mounted on shaft 26 and projecting therefrom in the oppositedirection to arms 26 is a pair of spaced fingers 29 and 29 Spring 2.9 onshaft 26 shown Untied bundles of newspapers Sprocket 16 on the shaft ofroller 8 is rotated by 3 in Figure 8 causes finger 29 to move against afixed block 50, pressing the paper web against this block andeffectively preventing the paper from slipping back during the cuttingoperation hereafter described.

In operation the bundle or stack of newspapers is carried by section Aof the flight conveyor from left to right in Figure l of the drawingtill the forward. portion of the bundle contacts switch arm 30 ofcontrolswitch CS1 which extends above the conveyor in the path' of thebundle. as hereafter described but it is generally located at'the end ofsection A and just in front of section B. The

switch arm 30 is caused to swing from the position shown in full linesin Figure l to the position shown in dotted lines in Figure l as thebundle progresses along the conveyor. Operation of the switch CS1 makesan electrical circuit and closes arelay preparing a circuit for otherswitches which will be actuated as the bundle advances further. At thispoint the free end of the web 19 of wrapping paper is lying over theroll 8 with its free or severed edge just beyond or to the right of theroller, but it is not being fed.

As the bundle advances its forward edge engages the upper section of theweb of wrapping paper and at approximately the same time contacts switcharm 31 of control switch CS2. Switch arm 31 is pivoted at one side ofthe conveyor as illustrated in Figure l similarly to switch arm 30 andwhen contacted by the bundle will be moved from the position shown infull lines to the position shown in dotted lines.

Switch CS2 electrically, through a three-way solenoid valve illustratedin Figure 9 and hereafter described in detail, allows air to enter thecylinder 28 and forces the piston upward, forcing roller 25 in contactwith roller 8 causing'the webof wrapping paper to feed. The web nowfeeds at the same'speed that the bundle is moving forward and results inwrapping paper moving forward under the bundle. The amount of webprojecting ahead of the bundle is controlled by the point at which thebundle engages switch arm 31 and actuates the switch CS2. The bundle andwrapping paper move forward to gether until the back end of the bundlepasses beyond switch arm 30 allowing the switch CS1 to return to itsoriginal position. The location of switch arm 30 controls the length o fweb projecting behind the bundle.

It is obvious that mechanical means could be provided for measuring thelength of wrapping paper to be fed to each paper, and that a singleswitch operated by the paper could be substituted for the switches CS1and CS2. Such single switch would merely start the web feedingmechanism. Mechanical means would operate the cutting mechanism after apredetermined number of revolutions of the paperfeed roll. This wouldnot automatically vary the length of the web for different lengths ofbundle, as is done by the electrical means herein described. I i

The following means is provided for severing the paper web after apredetermined length has beenfed beneath the bundle. Return movement ofthe switch3il cornplctes an electrical circuit which operates athree-way solenoidvalve and a three-way slave air valve, as here, afterdescribed, allowing air to enter behind thepiston pendently, of itthrough sprocket 16 as previously described.

Fixedly mounted on the shaft 36 and projecting from each end thereof arearms 37.. (See particularly Figure 8.) Secured to the ends of the arms37, and extending The position of this switch CS1 can be adjustedbetween them is a ledger or cutter bar 38. Rotation of the pinion 35causes the cutter bar to rotate clockwise from its normal position shownin Figures 6 and 8 to the position shown in Figure 7. As the cutter barfollows its circular path it rises from a position below and in front ofthe roller 8 to the plane or surface of the conveyor section B, abovesaid plane and downwardly crossing said plane again and terminatingbelow the plane and out oft'he p ath of the bundle which has just passedover that section of the conveyor. In the course of its downwardmovement it contacts the web of wrapping paper, which is being fed overthe roller 8 and which extends beneath the bundle which has just passedover the roller, and forces the web down against the saw-toothedknifeedge 39 which is mounted in a frame and held in position by aclamping bar 41 and extends across the conveyor section B at least adistance equal to the width of the paper web to be cut. During thisoperation the portion of the paper web where the cut is to be made isheld by the pressure roller 25 bearing against the roller 8; by theinertia of the bundle beneath which the free end of the web is stillheld; and by the friction of the rollers on the roller fiight conveyor.Forcing the paper over the saw-toothed knife-edge 39 results in a cleanrapid cut. Satisfactory results may be obtained even if the knife-edgeis dull and even if the ledger or cutter bar has a wide clearance fromthe knife.

Continued forward movement of the rack 34 carries the cutter bar pastthe severing position until rack 34 engages operating button 42 ofswitch 42 which opens an electrical relay operated by switch 42 andrestores the air valve controlling cylinders 32 and 28 to their originalposition. This results in the cutter bar returning to the position shownin Figures 6 and 8 and the paper feed roller or tension member 25returning to the position shown in Figure 7 so that finger 29 willcontact the paper and press it against block 50 and prevent the cut endof the web from slipping back out of the guide members 23 and 24.

The bottom wrapper has now been applied to the bundle and the bundlepasses over the conveyor section C to either the tying machine oranother conveyor. The length of the tail end of the wrapper beyond thebundle is controlled by the position of the end of switch lever 30 withrespect to the paper severing knife. Both the switches CS1 and CS2 areslidably mounted on the frame 1 and can be adjusted for the properposition of the switch levers. Also by means of cams in the switches theangle at which the switch arms 30 and 31 are actuated can be adjusted.Thus the wrapper length at either end of the bundle is readilyadjustable,

To provide a guard for the knife-edge 39 and thus prevent the operatorfrom accidentally being cut by the knifeedge, a safety bar 43 as shownin Figures 6, 7 and 8 is provided. A sheet metal guard 43 shown inFigure 8 is attached to the front of the safety bar. The edge of thisguard is located close to roller 8 to prevent the cut end of the paperweb from following around the roller 8. The safety bar is supported bytwo arms 44, 44 rotatably mounted on shaft 36. When the cutter bar is innormal position rearward extensions 37 of arms 37 contact the safety barbringing it up above the knife 39, thus preventing accidental contactwith the knife. When the cutter bar is actuated, the extensions 37'rotate and release the safety bar. Spring 49 pulls the safety bar downto the position shown in Figure 7 allowing the cutter bar to force thepaper past the knife. The return of the cutter bar brings the safety barup into safety position.

To prevent a bundle on conveyor section A from passing onto conveyorsection B before the previous bundle and wrapper has been cleared, astop cylinder 45 is provided as shown in Figures 1, 2, 8 and 9. When theend of the switch arm 30 has cleared the bundle and the cutter barcylinder is actuated, air is admitted .under the piston of cylinder 45by a three-way solenoid valve forcing the piston rod 45 up between rolls6 and 7 and stopping the forward movement of any following bundles ofpaper. When the bundle in the machine is moved to a point that willallow another bundle to move onto conveyor section B and accept awrapper and have the wrapper cut off, then the end of switch arm 31 justclears the end ofthe bundle allowing the switch to return to normalposition. This breaks the circuit to the solenoid controlling air tocylinder 45 and a spring returns the stop rod to its normal position andallows the succeeding bundle to enter the machine. This feature isvaluable and is necessary where the discharge from the roller flightconveyor may be blocked, such as when the machine is used as anautomatic feeder. When there is no chance of the bundle, leaving theconveyor, being restrained this feature may be omitted.

In order to be sure that there is a positive drive pulling the bundleover the wrapper applying mechanism, a fixed brake shoe 51 under the toprollers of the roller flight conveyor C contacts these rollers. 'Whilethese rollers travel with their operating chains, each rollerindividually rotates freely. The applicationof friction to the undersideof these rollers as they are travelling causes them to rotate so thatthe top surface of the roller flight conveyor C will be rotating attwice the normal speed of the conveyor. The driven rolls and the wrapperapplying mechanism as mentioned earlier run at progressively highersurface speeds and the final driven roll 9'runs at a speed slightly lessthan the top surface of the rollers of flight conveyor C when theycontact the brake shoe. This results in a receiving conveyor C, thesurface of which operates slightly faster than the fastest portion ofconveyor section B, so that there is a constant pull on the bundle ofpaper and wrapper which smooths out any wrinkles that may form as thewrapper is being applied.

The finger 29 normally presses the paper against block 50 to prevent theend of the web of wrapping paper from slipping back after it has beencut and when it is not being fed as shown in Figure 7. In order to movethe finger 29 out of contact with the block 50 in order to permit theweb 19 to be manually threaded between the guides 23 and 24 there isprovided manually operated means comprising an operating arm 46 securedto a shaft 47 rotatably mounted on frame 1 and extending across themachine between finger 29 and finger 29 (see Figures 1, 6, 7, and 8).Secured to and projecting from shaft 47 is an arm 48 which, when theshaft 47 is rotated clockwise, will engage finger 29 and force finger 29to swing away from the block 50 against the pressure of spring 29 Thisleaves a free path for the paper to be threaded up between guides 23 and24 (Figures 2 and 8). Immediately the paper is fed up, the shaft 47, 48may be rotated anti-clockwise allowing the finger 29 to contact thepaper and prevent the end of the web from slipping back.

Two rolls of wrapping'paper are provided so that if a roll is used upduring normal operation, paper from the second roll can be threadedthrough in a very short time whilethe first roll is being replaced.These rolls are mounted on identical carriages side by side beneath themachine. Since the carriages are identical only the mounting for roll 21wil be described. The rolls of paper are carried on shaft 52 mounted inslots on hearing blocks 53 which in turn are mounted in frame 54. Thisframe is mounted on an extendable drawer guide having, at the outer end,castors 55 which allow the carriage to be pulled out from beneath themachine for placing a new roll of paper and then returned to theoperating position under the machine.

As shown in Figure 3, the carriage is locked in closed position byhandle 56 having a locking cam 57 which engages finger 58 secured toframe 1. When in closed position theinner end of the roll 21 of wrappingpaper will be held against brake block 59. This brake block is carriedon arm piyotally. mounted at its upper end and ally constant.

Roller 22 is an idler roller to guide the web of paper when the roll ofpaper 20 is being used and roller 22' is a similar idler roller to guidethe web of paper when the roll of paper 21 is being used. This is theonly purpose these rolls serve.

Figure 10 shows diagrammatically the electrical and pneumatic systemswith various parts of the machine denoted by symbols in order to give aclear description of the sequence of operation of the various parts.

The switch 62 is the general circuit switch which is closed when themechanism is in operation. Other switches may be provided for stoppingthe machine in an emergency. I

Control switch CS1 has two positions, normal and conditioned. Controlswitch CS2 has two positions normally open and closed. Both are operatedby contact of their switch arms 30 and 31 with the bundle. Switch CS1does not actuate anything until switch CS2 is closed.

The bundle first conditions CS1 then closes CS2 thus completing circuitthrough conditioned switch CS1. This (a) actuates normally closed airvalve 65 to operate piston of air cylinder 28 of the paper feed meansand (b) closes relay '63 through normally closed switch 42.

When thebundle clears switch CS1 switch CS1 returnsto normal. This (a)opens valve 66 to operate cylinder 45 and forces piston rod 45 up to actas a stop, and (12) makes circuit through previously closed relay 63 toclose normally open valve 67 and open slave valve 68 to actuate piston33 in cylinder 32 to operate the cutter by means of a rack 34 and pinion35.

At the extreme end of its stroke rack 34 strikes and opens normallyclosed switch 42. This breaks the circuit to the operating coil of theclosed relay 63, opening the relay, with the result that the solenoidair valve 65 operates (a) to exhaust air from cylinder 28 to permit itspiston 28 to return to normal position and stop paper,

ly close-d switch CS1 to solenoid valve 66, and actuating' said valve toexhaust air in cylinder 43 to permit stop to drop.

It will be noted that the cutting mechanism will not operate unless bothcontrol switches CS1 and CS2 have been actuated by the bundle. This is asafety feature which prevents accidental operation of the cutter.
